Atlas Copco presents innovative screw vacuum pumps at glasstec 2018

The functions and properties of glass are becoming increasingly diverse and smarter. The demands placed on glass production systems are also increasing accordingly. This not least includes vacuum technology, which forms a central component in the production and processing of glass products: For example, the evacuation of glass moulds, the coating of architectural glass or bottling under vacuum ensures high product quality and process productivity. In addition, vacuum lifters guarantee the safe internal transport of heavy and sensitive glass parts. Atlas Copco will be presenting its new variable speed drive vacuum pump series GHS 3800-5400 VSD+ at glasstec (Hall 15, Stand C03) precisely for such applications with a high vacuum requirement.

With the introduction of these new screw vacuum pumps, Atlas Copco underlines its commitment to sustainable glass production. In December 2017, the vacuum supplier therefore expanded its portfolio with the modern GHS 3800-5400 VSD+ vacuum pump series. Thanks to their long service life and greatly improved oil cooling and retention, these robust pumps contribute to savings in production processes. Compared with existing technologies, their use has resulted in significantly reduced life cycle costs.

The GHS VSD+ series was developed according to Atlas Copco's proven philosophy and is therefore designed as a durable plug-and-play system in a single housing. "The energy efficient units deliver higher volume flows per hour and kilowatt power consumption than vacuum pumps with comparable performance," explains Christoph Angenendt, Communications Manager Industrial Vacuum at Atlas Copco. It therefore makes particular sense to convert several decentralized pumps to a central vacuum supply. With a GHS VSD+ system, users can significantly increase their productivity; Atlas Copco reports that energy savings of up to 50% can be achieved in glass production compared to conventional rotary vane vacuum pumps. "The payback time for a converted system is correspondingly short," adds Christoph Angenendt.

During development of the GHS 3800-5400 VSD+ Atlas Copco's design engineers drew from the experience with the established GHS 350-900 VSD+ and GHS 1300-1900 VSD+ series. They also feature high efficiency and reliability and are available as a compact, user and service-friendly package. The screw element at the heart of the pumps offers a lifetime guarantee, while intelligent turbo and humid versions ensure trouble-free performance even in the most difficult application environments. The coarse vacuum pumps are optionally equipped with air or water cooling. An energy recovery option makes it possible to use the work of the IE3 high-efficiency motor. A clear advantage in ergonomics: the oil retention improves the quality of the exhaust air compared to alternative technologies. "This results in a cleaner and cooler working environment," says Christoph Angenendt, explaining the benefits for users.
